This invention relates to container constructions and inparticular to the manufacture of containers for the packing of foodstufi', such as candy and the like.

A particular object of my invention is to provide a container having, a sight opemng therein through which the contents of the same may be displayed to advantage and for the purpose of determining the flavor by color of certain articles of food of shades of color of merchandise sold' in the container without the necessity of unwrapping the same to remove the cover which, in the case of foodstufi', is objectionable in that the foodstuff may quickly spoil when air is admitted to the contalner.

A still further object of my inventlon and an equally important one, is the production of a container made from paper tubing in which a sight opening is provided, the method of constructing the container being a feature of my invention.

A still further object of my invention is to provide a method of forming a container which may be made up in long, tubular form and may be cut up to provide single containers, the construction permitting the applicationto a container of a wrapper by t e packer of the merchandise, so that the containers and wrappers may be sold se arately to the packer or the containers may he made up completely by the manufacturer and shipped to the packer.

Changes and variations may be made in the construction shown and described without departing from the principles of the invention or sacrificing its chief advantages; hence such invention is not to be confined to the structures shown in the accompanying drawmgs;

Figure 1 is a view of a tubular member constructed in accordance with my invention and illustrating a preferred form of construction before the tubular member is cut upto provide individual containers.

Figure 2 is an enlarged section on the line 22 of Figure 1 and illustrates the method of construction.

Figure 3 is a view illustrating a container made up from, one of the sections of the tubing illustrated in Figure 1 having applied thereto, a wrapper which serves to seal both covers on ends of the container.

Figure 4 is a modified form of construction in which aligned openings are provided in the tubing which are covered by a sin le strip of cello hane disposed between time wrapper and t e tube.

Figure 5 is an enlarged section taken on the line 55 of Figure 4 and illustrates the constructionl Figure 6 is a View similar to Fi re 4 showing the use of individual pieces 0. cellophane that are used in each individual 0 ening instead of the strip illustrated in ig-' ure 4.

Figure 7 is a further modified form of construction in which a single strip of cellophane is used that is disposed between the plies of tubing in position to cover the opening formed therein.

Figure 8 is an enlar line 88 of Figure struction.

Figure 9 is' a modified form of container of rectangular shape, it being understood, of course, that the shape is not a feature of the invention, in which one end wall is provided with a sight opening through which the color of merchandise such as yarn or the like may be shown without the necessity of 'ungvrapping or uncovering the container, an

Fi ure 10 is an enlarged section taken on the line 1010 of Fi re 9 illustrating the 35 construction at one en of the container.

Referring to the drawings in detail and in ed section taken on the to illustrate the conparticular to Figures 1, 2 and 3, my inven- I tion contemplates the manufacture of a container of preferred form through the medium 90 of a tubular construction, the paper tubing or rather, the cardboard tubing, it being understood that the particular formation of the tubing insofar as its method of wrapping is concerned, is not a feature of my invention, it being suflicient to note that alternate layers of'the cardboard are wrapped spirally about" each other in opposite directions so that'the tube will hold to ether-and resist crushing. The outer ply o tubing 5 is wrapped as indicated while the inner ply is wrapped spirally in the opposite direction,

the inner ply being indicated by the, numeral 6, although it is to be understood that any number of plies may be employed to carry templated, being the piercing of the tube to v as.

provide sight openings 8 at spaced points ongitudmally of the tube but in staggered, spiral relation to each other, as indicated in Figure 1. After the inner plies 6 of the tube have been made and the tube is thus artially completed, the tube being indicated y the numeral 9, a spiral wrapping of transparent, cellular material in strip form 10, commonly known as cellophane, is employed to cover the openings 8 that have been made in the inner'plies of the tubing.

It is understood, of course, that my improved container is made by suitable machinery and the steps of manufacture are carried out in proper sequence and after the transparent material 10 has been placed in position, the outer layer or winding of cardoard "or tube forming material 5 is.wound over the inner ply or plies 6, this outer ply having openings 11 cut therein to coincide with the openings 8 in the inner ply 6 and inasmuch as the inner surface of each of the plies of the tubular member with the exception of the inner ply, are coated with a cementitious or sticky substance, the strip of transparent material 10 will be securely held in position, and of course the plies of the tube will be secured solidly together.

' An important feature of my invention is L the staggering of the sight openings in that the spiral strip 10 of transparent material which is wound on a spiral of greater pitch than the tube material is not wasted, that is, if

' the transparent material 10 were to be wound at the same pitch as is the plies of tubular material, it is quite obvious that a piece of material 10 long enough to extend completely around the tube would be used for each opening were the openings in alignment but by staggeringthe openings, it is, possible to use a single strip of material-without interrupt.

ing the manufacturing operation. In other words, during the formation of the tube and the punching thereof, the strip 10 is automatically wound in position and it is possible to do this because it also extends spirally.

The holes are cut in the tubular material at any time-but preferably just before the cellophane is applied and the cellular material may be placed between the plies of the card board or tubular material or may be placed on the outside of the tubular material but if positioned between the plies is preferable, in that it is securely held in position and acts to seal the sight opening.

aeeaaea Another form of my invention is the provision of sight openings 13 in alignment and the use of a longitudinally extending strip of transparent material 14 to provide'windows for the sight openings 13, the tube 15 being wound in the same manner as explained in connection with the tube illustratedin Figures 1 to 3. In providing this form of tubing, however, it is necessary to start the winding operation of the tube while'the longitudinal strip 14 is applied which slows up production and adds to the cost of the containers. The tubes, after they are completed are cut into sections, the line of separation being' indicated by the numeral 15 so that individual containers are provided having a sight opening 8 therein, which sight opening is closed by the transparent materlal.

In Figure 3, a completed container is illustrated in which an outer wrapper 16 has been applied that holds in position end covers 17 that are placed over the ends of the tubular container or receptacle 18. lhis wrapper may be fancifully decorated and is provided with an opening 19 that corresponds with the sight opening 8, so that the merchandise within the container is effectively displa ed and, in the case of candy, the flavor can e determined by the .color of the merchandise or in the case of non-edible merchandise, the shade of color may be determined without opening the container.

Figure-6 shows a further modified form of my construction in which the transparent material 20 employed in covering the sight opening 21 is employed in pieces for covering each individual sight opening, the tube 22, as heretofore, being cut up on the'lines 23 to provide individual containers, which may be wrapped and filled for use in the trade, as explained.

Figure 7 illustrates a still further modified construction in which the strip of transparent material 25 extends longitudinally of the tube 26 but is disposed between the plies 27 and 28 of the tubing to cover the sight opening 29.

Figures 9 and 10 show the use of a rectangular box 30 having a cover 31 over which is placed a moisture-proof wrapping 32 of either transparent or opaque material. The box 30 is provided with a sight opening 33 and on the front surface of the box, there is secured as by glueingor any other suitable means, a strip of transparent material 34 which provides a window for the opening 33. If an opaque wrapp'er'32 is employed, this wrapper is provided with a sight opening to register with the opening 33 in the box so that the contents of the box can be displayed .aud shade of yarn may be exhibited through the sight opening 33 without taking the lid off the box which might be detrimental to the Y wrapper.

or container, is that when the boxes are stacked on a shelf, it would not be necessary to remove them in order to determine the shade or nature of the contents, which can be determined through the sight opening.

It is evident, therefore, that I have provided a container which may be made up in various forms having sight openings therein which containers are so constructed that the same may be produced at a minimum cost with a resultant saving to the consumer and the container is provided which displays the contents and the construction of which permits it being completed at the factory at which it is made or allows the container to be made up and shipped with the wrapper to the packer of the merchandise who appliesthe In some instances, the tubing may be wrapped or manufactured with the opening therein and the wrapping maternal or mdividual Wrapper for each container that has been cut from the tube may carry an opening which is covered with the transparent material so that when the wrapper is applied, the opening therein will register wlth the opening in the tubular container and m this way, the contents of the container W111 be effectively displayed.

It is to be understood that the slght opening will be covered with the transparent material before the container is filled with the merchandise.

My invention is not to be restricted to the precise details of construction shown since various changes and modificationsmay be made therein without departing from the scope of the invention or sacrificing the advantages derived from its use.

What I claim is 1. The method of making containers which consists in spirally winding material to form a tubular body portion, cutting spaced sight openings therein, closing said sight openings with a transparent material, and then cutting the body into sections each having a sight opening.

2. The method of making containers which consists in spirally winding material to form a tubular body portion, cutting spaced relatively staggered sight openings therein, closing said openings with a transparent strip of materia and then cutting the body into sections each having a sight opening.

3. The method of manufacturing containterial at such a spiral pitch that the sight openings are closed by said transparent material.

5. The steps in the manufacture of containers which consists in spirally winding a tubular body, cutting longitudinally spaced sight openings in the body, winding about i said body a strip of transparent material at ers which consists in cutting sight openings in a tubular body, closing said openings with a transparent material, and then cutting the body into sections each having one of said sight openings.
